For the production of compounds of formula (I), compounds of formula (II): ##STR14## in which Y is chloro or a radical of the formula NHR, and

X, r and R.sup.1 have the meanings given above may be reacted with an amine of the formula:

R--NH.sub.2.

reaction conditions which affect the exchange of the chlorine atom(s) include the temperature, the amine component, the molar ratio of the reactants and any diluent or solvent or acid-binding agent used. Amines of low boiling point may of course be reacted under superatmospheric pressure. The reaction with the amine is conveniently carried out at elevated temperature, a temperature of from about 0.degree. to 110.degree. C being adequate for the exchange of the first chlorine atom depending on the basicity of the amine, while temperatures in the range from about 60.degree. to 180.degree. C being advantageous for exchange of the second chlorine atom.

Amines of high basicity react more rapidly than those of low basicity; when exchanging the second chlorine atom it is advantageous to use an excess of amine (more than 10 percent), whereas the first chlorine atom reacts immediately with a molar amount of amine. Examples of suitable diluents or solvents which may be added are alcohols such as methanol, ethanol or isopropanol, glycols and glycol ethers such as methyl glycol, ethyl glycol or butyl glycol, hydrocarbons and halohydrocarbons such as benzene, toluene, ethylene chloride, chloroform, trichloroethylene or chlorobenzene, and also acetone, tetrahydrofuran, dimethylformamide, N-methylpyrrolidone or dimethylsulphoxide. The presence of water does not cause any disturbance.

The addition of acid-binding agents is advantageous because then the total amount of amine to be reacted is available for the exchange. Substances which do not themselves react with the chloropyridine derivatives are suitable as acid-binding agents; for example tertiary amines such as triethylamine, tributylamine, triethanolamine, ethyldiisopropylamine, caustic soda solution, sodium carbonate, magnesium oxide or calcium carbonate are suitable. In the case of inexpensive amines, an excess of the amine to be reacted may also serve as acid-binding agent.

Compounds of the formula (Ib); ##STR15## in which R has the meanings given above are of particular industrial significance.

Examples of preferred radicals R containing oxygen are:

Examples of preferred oxygen-free radicals which are preferably used in combination with an oxygen-containing radical R are besides H:

C.sub.2 h.sub.5, c.sub.3 h.sub.7, c.sub.4 h.sub.9, ##STR20## ch.sub.2 c.sub.6 h.sub.5, c.sub.2 h.sub.4 c.sub.6 h.sub.5, c.sub.3 h.sub.7 c.sub.6 h.sub.5, ##STR21## c.sub.6 h.sub.5, c.sub.6 h.sub.4 ch.sub.3, c.sub.6 h.sub.4 och.sub.3.

the new coupling components are outstandingly suitable for the production of azo dyes by reaction with diazotized amines. The dyes which can be obtained in this way are distinguished by excellent fastness properties and by unusual brightness for azo dyes.

The following Examples illustrate the invention. Parts and percentages referred to are by weight unless otherwise stated.

EXAMPLE 1

187 parts of 2,6-dichloro-3-cyano-4-methylpyridine is suspended in 500 parts by volume of methanol. 80 parts of 2-hydroxyethylamine is then added at 40.degree. to 45.degree. C followed by 100 parts of triethylamine. The mixture is stirred for five to six hours at 45.degree. to 50.degree. C, about 250 parts by volume of methanol is distilled off and the residue is diluted with 1000 parts by volume of water. After acidification with 50 parts of concentrated hydrochloric acid, the whole is stirred for 1 hour, the deposited precipitate is filtered off, washed with water until neutral and dried. About 210 parts of a colorless powder of the formula: ##STR22## is obtained. The powder contains a minor amount of a product of the formula: ##STR23## The mixture melts at 115.degree. to 120.degree. C.

125 parts of this powder is stirred with 300 parts by volume of methoxyethylamine for six hours under reflux.

Excess methoxyethylamine is then extensively distilled off so that the temperature may rise to 130.degree. C and the whole is then diluted with 500 parts of water. The mixture is stirred for one hour at 0.degree. to 10.degree. C and the deposited precipitate is filtered off, washed with water and dried. The main product has the formula: ##STR24## and there is a minor amount of a product having the formula: ##STR25## The product is colorless and melts at 75.degree. to 78.degree. C.

EXAMPLE 2

A suspension of 50 parts by volume of methanol, 22 parts of norbornylamine, 37 parts of 2,6-dichloro-3-cyano-4-methylpyridine and 25 parts of triethylamine is stirred for six hours at 40.degree. to 50.degree. C. Then about 200 parts by volume of ice-water is added, the whole acidified to pH 1, and the precipitated product of the formula ##STR26## (which still contains a small proportion of 2-chloro-3-cyano-4-methyl-6-norbornylaminopyridine isomers) is filtered off, washed with water and dried. About 45 parts of a colorless powder is obtained which melts at 110.degree. to 112.degree. C.

45 parts of the moist powder is heated at 130.degree. C to 140.degree. C with 50 parts of the amine of the formula:

H.sub.2 N--CH.sub.2 --CH.sub.2 --O--CH.sub.2 --CH.sub.2 --OH

the water being allowed to evaporate. After stirring for 5 hours at 130.degree. to 140.degree. C the reaction is completed. The whole is allowed to cool and is acidified with 130 parts by volume of acetic acid. A solution of the coupling component mixture of the formulae: ##STR27## and ##STR28## is obtained, the amount of the product of formula (II) being small.

When the mixture thus obtained is coupled with p-nitroaniline a dye is obtained which dissolves in dimethylformamide to give an orange solution.

EXAMPLE 3

A mixture of 300 parts by volume of N-methylpyrrolidone, 150 parts of 2,6-dichloro-3-cyano-4-methylpyridine, 115 parts of p-anisidine and 90 parts of triethylamine is stirred for from six to 7 hours at 70.degree. C. It is then poured while stirring onto 1500 parts of ice-water and acidified with hydrochloric acid to pH 1. About 220 parts of a colorless product of the formula: ##STR29## is obtained which is isolated by filtration, washing with water and drying. The powder contains a minor amount of a product of the formula: ##STR30## The mixture melts at 147.degree. to 150.degree. C.

EXAMPLE 4

50 parts of 2,6-dichloro-3-carbamoyl-4-methylpyridine is stirred with 75 parts of propanolamine-1,3 for 10 hours at 90.degree. C. The mixture is precipitated with water and acidified to pH <O. The insoluble residue is filtered off, washed with water and dried. The colourless powder melts at 210.degree. C and probably has the formula (I): ##STR31## The filtrate has caustic soda solution added to it until the pH is from 5 to 6. A crystalline precipitate is thrown down which probably has the formula (II) ##STR32## This is filtered off, washed with water and dried. The product (II) thus obtained also contains traces of the product of the formula (I) and melts at 150.degree. to 160.degree. C.

If the reaction mixture is precipitated at pH from 6 to 7, a mixture of the two isomers is obtained which has a melting point of about 143.degree. C.

When 2,6-dichloro-3-carbamoyl-4-methylpyridine is treated analogously to the method described in Example 4, mixtures of substituted 2-aminopyridines and 6-aminopyridines are obtained, the amount of 2-amino-3-carbamoyl-4-methyl-6-chloropyridine derivatives being only slightly greater than that of the 6-aminopyridine isomers in question.

The physical properties given in Table 1 relate to mixtures.

When 2,6-dichloro-3-cyano-4-methylpyridine is treated by a method analogous to those described in Examples 1 to 3, there are obtained (by exchange of one chlorine atom) mixtures of 2-amino-3-cyano-4-methyl-6-chloropyridine and 2-chloro-3-cyano-4-methyl-6-aminopyridine derivatives, the proportion of the 2-chloro-3-cyano-4-methyl-6-amino isomers being clearly less.

In the case of pyridine derivatives which contain a carbamoyl group the reaction has to be carried out however at the lowest possible temperature because otherwise hyrolysis and/or decarboxylation of the --CONH.sub.2 group may take place.

The Examples described in the above Tables are prepared by always first introducing the radical R.sup.1.

EXAMPLE 357

25 parts of the coupling component of the formula: ##STR180## is stirred with 75 parts of 90 percent sulphuric acid for six to eight hours at 80.degree. to 100.degree. C. The reaction mixture is then precipitated on 500 parts of ice, adjusted to pH 4 to 6 by adding caustic soda solution and extracted with ethyl acetate. After the extractant has been evaporated about 20 parts of the coupling component of the formula: ##STR181## is obtained as a dark oil. A red dye is obtained therefrom after coupling with diazotized p-nitroaniline

EXAMPLE 358

30 parts of 2,6-diamino-3-cyano-4-methylpyridine is stirred with 200 parts by volume of concentrated sulphuric acid for ten hours at 50.degree. C. The whole is then allowed to cool, 250 parts of ice is added and it is left overnight. The deposited precipitate is filtered off and washed witht acetone. After drying, 36 parts of a colourless powder of the formula: ##STR182## is obtained which melts at 250.degree. C with decomposition.

The free base of the formula: ##STR183## is obtained from the salt by a conventional method.
